Energy dashboard: toggle between cost and consumption

It would be very helpful if the energy dashboard allowed you to view the main day/week/month/year graph in either kWh or cost ($/£/€ etc). This would mirror other energy dashboards like the UKs smart meter displays. These let you switch between consumption and cost. Most people have no frame of reference for how much 7kWh is, but they understand how much £2 is.

It would also be incredibly helpful to see the nderlying price change. This week the UKs energy prices nearly doubled overnight, so it would have been good to be able to see this jump.
